Variational Option Discovery Algorithms

Paper Abstract: “We explore methods for option discovery based on variational inference and make two algorithmic contributions. First: we highlight a tight connection between variational option discovery methods and variational autoencoders, and introduce Variational Autoencoding Learning of Options by Reinforcement (VALOR), a new method derived from the connection. In VALOR, the policy encodes contexts from…

Nature review-epigenetics

Techniques that interrogate DNA methylation, histone modifications or chromatin conformations are enabling unprecedented analyses of epigenomes, including at the single-cell level. The articles in this series discuss insights into chromatin biology and the components and mechanisms of diverse epigenetic processes in health and disease, from fundamental roles in gene regulation to broader biological phenomena such…
